Abstract
Employing of aniline dimer (N-phenyl-p-phenylenediamine, NPD) as the starting monomer, polyaniline was electrochemically synthesized on the surface of glassy carbon electrode in acetonitrile-aqueous mixing solutions(20% by volume)containing 1 mol·L-1 HClO4. Experimental results demonstrated that the polymerization of NPD occurs at the potentials about 0.2 V lower than those of aniline monomer. Furthermore, the resulting polyaniline has higher morphology controllability than those synthesized by using aniline as the stating monomer. The uniform polyaniline nanoparticles (30 nm in diameter), ultralong nanowires (length > 5 μm, 50 nm in diameter) or large area nanosheets (4 μm in length, 2 μm in height, 30 nm in thickness) can be prepared by using step-wise galvanostatic method when the concentrations of NPD monomer was 1, 5 or 10 mmol·L-1, respectively.
